Abstract

Nano-sized materials have many unique physical and chemical properties. Among the many synthesis methods for the production of nanomaterials, photochemical synthesis plays a very important role. Using the photochemical synthesis method, nano-sized metal, semiconductor, bimetallic and semiconductor composite materials and even 2D particles can be synthesized. Various surfactants and polymers are frequently used in the photochemical synthesis of metal nanoparticles to stabilize the resulting nano-sized particles. Apart from these, other compounds such as ionic liquids, thiol groups and DNA macromolecules can also be used for this purpose. It is possible to adjust the morphology of nanoparticles by varying the molar ratio of metal ions and stabilizers and the concentration of reducing agent.

In this study, the synthesis and characterization of the thioxantone disulfide derivative as photoinitiator and at the same time as a photoreducing agent was performed. Then, the synthesis of Au/Pt bimetallic nanoparticles in both solution and polymer matrix by photochemical method was performed. Au/Pt bimetallic nanoparticles were prepared in a short time of period in a single step. The size distributions and stability of the nanoparticles were analyzed by DLS and ZETA potential measurements. Potential applications of Au/Pt bimetallic nanoparticles range from nanosensors to drug delivery systems.
